gmail login Firefox has detected that the server is redirecting the request

Redirect Loop: Firefox has detected that the server is redirecting the request for this address in a way that will never complete. above was the error i was getting when i tried to login to my custom domain email ie gmail account and even i had same problem when i tried to log into my gmail account (mail.google.com).

So what might be the problem? though this issue comes for variety of reason first time when i got this issue a simple procedure of clearing the browser cache and cookies solved the problem

but recently i ran into same problem again i cleared the browser cache and cookies still problem remained i tried other browsers but in vain, i also flushed the DNS of system still i was not able to login to my gmail account i also tried in more than two other browsers on my system IE and Google chrome i got same behavior but issue got resolved only after restarting the system.

bottom line i really don't know why i got this issue but one of the below technique solved my problem each time.

1. First Clear browser cache and cookies and try in other browsers in your system
2. Flush the DNS cache of your system.
3. Restart your system.

If problem still persists and you were able to resolve it then do leave a comment so that others can benefit and know other causing issues for this problem
